Based on the list in the opening post, I have a few remarks:
- I don't get the use of playing 2 plains and only 1 island. The deck looks like more island intensive than plains, in particular with Fathom Seer. Same remark on the fetches choice.
- it's probably because you overlooked it but Vesuvan Shapeshifter looks far better than Knight of the White Orchid. See my previous post.
- In general Enlightened Tutor sideboards are bad, for 3 main reasons: 1/you need redundancy in your SB. For instance, once Ghostly Prison has been dealt with, you won't find another one even in late game 2/ in a lot of MUs you won't appreciate to do 2 for 1 for a SB card, even Ichorid 3/ all the SB cards are of the same family: artifacts and enchantments, meaning that in best case, bringing hate for your hate in g3 is easier, in worst case
Reverent Silence and/or
Shattering Spree will net your opponent CA. I've been seduced by ET SBs too at some point and I finally disliked them compared to a full SB.
- The MD plays only 17 blue cards. It's very low.
- The SB plays 0 blue card. You SBing has to be very tricky...
